" LUBRI'CATOR..

Be it known that I, HJALMAR A'. Swanson', a citizen of the United States of America,

vand a residentof Chicago, in the count-y of Cock, State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invent-ion relates to the valveless anultiple delivery typeof force feed lubri- 4cators employed in the lubrication of automobiles and the like, and has for its object to provide a lsimpley and efficient structural arrangement .and combination of parts whereby the operation of the pump plungers and the change in unison therewith of the fiow of the lubricant is attained in a simple, effective and positive manner, all as will hereinaftermore fully appear.

In the accompanying drawings: Figure 1 is a sidey ele ation of the mechanism, with the inclosing tank shown in section. Fig. 2, is a detail horizont-al section on line -m, Fig. 8. Fig. 3, is a sectional plan view on line @JJ-', Fig. 1. Fig.- il, isa detail plan view of the fixed member of the pump mechanism. with the outlet pipes shown in section. Fig. is an inverted plan view of the movable pump casing, illustrating the inlet-outlet. ports of the same.` Fig. 6, is a detail horizontal section` on line a02-m2, Fig. 9. Fig. T, is a central longitudinal section on line ais-x3, Fig. 3. Fig. 8, is a detail .vertical section on line m*-'-w*Fig. 2, showing the pump parts 1,11 the suction or receiving position. Fig. 9, is a companion view showing the. parts in a delivery position.

Similar jreference numerals indicate like parts in the several views.

Referring to the drawings, 1 represents an openl top tank of any usual form, adapted to contain the supply of lubricant or other iuid to Abe pumped. A.

2 ,isu t-he removable cap or-:cQver of the tank, provided with the usual strainer inlet` opening 3, which in the present construction is located directly above the hereinafter described pumping mechanism, for the puri pose hereinafter stated. v

4, is thek fixed member of the pump having y attaching cars by which iti is attached -to the bottom web of the tank 1 in a raised position above the same as shown. I n the present improvement said fixed memberi- 4 carries a 5 vertical journal stem 5, and its upper surspecification of 'Letters raient.

face, which constitutes a seat for the here? inafter described ysemi-roltary pump casing, 1s formed with a series of alternating inlet and outlet ports 6 and 7 in concentric relation tothe axis ofthe aforesaid ournal stem 5. The above referred "tolinletports 6 are preferably straight vertical passages eX- tendingy through Athe fixed member 4 and opening at bottom into the tank chamber as.

shown. The outletports 7 are preferably of a U form, radially arranged and connected at their outer ends with individual outletpipes 8, which'in A turn extend out through an inclosing Wall of the tank 1, to the required points of delivery, as usualv in multiple delivery lubricators.

9 is the semi-rotary pump casing above referred to, and which has bearing upon the upper surface of the fixed member 4, and is held to its proper semi-rotary movement;` 'thereonby a central vertical bore which has engagement with the stem 5 of t-he fixed member 4:. Said casing is formed with a series of vertical. pump barrels 10, arranged in. concentric relation to the axis of the stem 5, and said barrels at their lower ends are provided with yertical inlet-outlet ports 11, adapted in the 'practical operation of the mechanism to alternately register with the inlet ports 6 and v'outlet lports T of the fixed pump member above described.

12 is'a plunger carrying head or spider arranged above the pump casing' 9 and formed with a central ver-tical bore by which it is guided on .the aforesaid vertical stem `5 of the fixed pump member L1, in a,

manner to permit of its semi-rotation in unison w1th the sehn-rotary Apump casmg 9,

, and in a rectilinear manner to and from said `plunger carrying head Said stems are of a less diameter than said' plungers, in order to provide bearmgshoulders at the1r point of intersection, which shoulders are" adapted for bearing engagement. with the head 12 in t-hevvdownward movement of the msm.
